The positive infinite power of e tends to infinity, the negative infinite power of e tends to 0, and the infinitesimal power of e tends to 1.

e = 2.7 1828 183

The natural constant is a constant in mathematics, an infinite acyclic decimal and a transcendental number, which is about 2.7 1828, that is, the formula is IIM (1+ 1/x) x, x→ < x > or iim (1+z).

e？ The origin of:

One of the most intuitive methods is to introduce an economic name "compound interest". Compound interest method is a method to calculate interest. According to this method, the interest will be calculated according to the principal, and the newly obtained interest can also be calculated, so it is commonly called "rolling interest", "snowballing usury" or "overlapping interest".
